<span style="text-wrap:nowrap;">I did not configure master/slave mode of bind9. And I serached the sources of bind9, but failed to find some keywords like zone_timer or zone_gotwritehandle.</span><br>
<span style="text-wrap:nowrap;"><br>
</span><br>
<span style="text-wrap:nowrap;">I have stucked on this strange problem for a few days.</span><br>
<span style="text-wrap:nowrap;"><br>
</span><br>
<span style="text-wrap:nowrap;">I found this zone file got updated in about 15 minutes when I made changes or restarted named, and this behavior seems match the docs bind9.readthedocs.io/en/latest/chapter6.html#dynamic-update, but I can confirm I DO NOT configure allow-update or update-policy. I even add "allow-update {none;}; // no DDNS by default" in the zone block of the problematic view. Is there any chances this configuration comes from other config file or named build options?</span><br>
<span style="text-wrap:nowrap;"><br>
</span><br>
<span style="text-wrap:nowrap;">I have also posted on <a href="https://stackoverflow.com/questions/77658310/zone-file-got-updated-via-named-process-unexpected" target="_blank">stackoverflow</a>, but without any response. </span><br>

I can confirm that I did not use or configure master/slave mode of bind9.
